Before you set off
Narrow valley lanes and exposed uplands require care. The Golden Road is a walking route, not a road to drive. Check current road closures, vehicle suitability and weather before travel. Driving time excludes stops and live traffic. The route follows through-roads; all visits off the line are independent optional detours.
